CNC Machine Safety

CNC Machine Safety

At Lowell using CNC machines is part of the daily routine, but it is extremely important that everyone remembers the proper safety rules while operating the machines. This will be a rundown of the basic safety rules that should be followed while working with or around a CNC machine. The two first general rules for CNC machine operation are 1. You should never work with a CNC machine without the proper training or the correct operator’s manual and 2. You should never try to program a CNC machine without the proper training as well.

CNC machines are built with the proper safety devices in place. These may include guards and other protective devices, it is important that these safety devices are firmly fitted in place at all times while the machine is in use. Some of these safety devices may include:

  • An Emergency Stop Button
    The emergency stop button is used to shut down the machine instantly. This button is located on the handheld unit, the control panel, and other places on the machine.
  • A Soundproof Casing
    The soundproof casing reduces the noise emitted by the operating section of the machine. It also protects the machine operator from the risk of flying tool fragments and any other flying objects.
  • The Curtain Guards
    The curtain guards are made out of PVC. These are designed to shield the machine operator from the risk of tool fragments or airborne chips.
  • The Guard Fence
    This part marks the maximum working area of the machine. This fence keeps the machine operator away from any moving parts.
  • The Contact Mats
    The operator uses this control to stop the CNC machine instantly. When he or she stands on the mat the machine stops instantly. This protects the operator from the moving parts.

There is also a list of personal rules that should also be followed outside of understanding the basic safety functions of the machines. You can feel free to add any additional rules that you think may apply to you and your coworkers.

DO:

  • Always ensure that you wear proper ear protection and a good pair of safety glasses when operating a CNC machine.
  • Ensure that your safety glasses are firmly in place every time you are closely observing the cutting tools.
  • Ensure that you wear suitable footwear such as safety boots at all times.
  • If you have long hair, ensure that you keep it covered when you operate the CNC machine.
  • Keep your hands away from any moving parts during machining processes.
  • Stand clear of the machine whenever it is operational. You should also warn any other people near the risk of being too close to it.
  • Whenever you are handling or passing tools, avoid touching the cutting edges.
  • Ensure that you turn the machine off completely and clean it whenever you have finished using it.

 

DON’TS:

  • You should never wear gloves while operating the CNC machine.
  • You should never wear jewelry or any loose clothing.
  • You should never try to reach into the machine while it’s running
  • You should never put your hands anywhere near the spindle when it’s revolving.
  • Never leave the machine when it’s not completely powered down.
